He who wins through fraud is not a winner.
There is no goodness in people who don't give advice, and there is no goodness in people who don't like to be advised
No amount of worrying can change the future. Go easy on yourself, for the outcome of all affairs is determined by God's decree. If something is meant to go elsewhere, it will never come your way, but if it is yours by destiny, from you it cannot flee.
If your ruler is just, then praise God; but if he is unjust, pray to God to rid you of him.
Do not be misled by hearing of anyone's reputation.
Do not depend upon the morality of a person until you have seen him behave while in anger.
